Bidirectional Power Converter

Bidirectional Power Converter

Bidirectional power converters (BPC) are the backbone of modern energy systems, enabling bidirectional energy flow between DC/AC ports (DC-DC or AC-DC). Optimizing energy utilization, enhancing system flexibility, and reducing costs by replacing two unidirectional converters with one integrated unit. Whether charging batteries from the grid, feeding stored energy back to the grid, or recycling wasted electricity, our BPC can provide precise control, ultra-high efficiency, and seamless mode switching. Our bidirectional converters are designed for industrial, automotive, residential, and utility scale applications, eliminating redundant hardware, reducing footprint, and supporting the transition to a net zero energy ecosystem.

Product feature and application

 

1. Support multiple devices of the same capacity

Two. It has a variety of output modes of constant voltage, constant current and constant power, and the voltage and current can be set.

3. Fast dynamic response speed, quadrant switching time ≤10ms, dynamic voltage stability time ≤5ms

4. It uses high-power IGBT, and the busbar uses a large-capacity capacitor with strong impact resistance.

5. The interior is equipped with a discharge resistor. When there is a fault or emergency stop, the resistor consumes the controller energy.

6. When the energy feedback is too large, it can be protected in time to prevent the equipment of both sides from being destroyed.

7. Adopting PWM rectification technology, the power factor is greater than 0.99 and the efficiency is greater than 92%.

8. Multi-stage filter circuit design, stable output

9. Mature digital control technology and perfect hardware filter circuit make the voltage and current ripple content low.

10. Using a large-screen LCD screen, multiple data that need to be monitored can be displayed, such as voltage, current, power, etc.

11. Perfect protection functions: overpower, overcurrent, overvoltage, short circuit, overheat, etc.

12. Its RJ45 communication interface makes remote operation and automation simpler.

FAQ

 

Q: What's the difference between DC–DC and AC–DC bidirectional converters?​

A: DC–DC converters transfer energy between two DC ports (e.g., battery ↔ EV power net), while AC–DC (PCS) converters connect DC storage (battery) to AC grids/loads (e.g., home grid ↔ battery storage).​

Q: Can the converter work with any battery type?​

A: Yes-our BPC is compatible with lithium-ion, lead-acid, and flow batteries. It integrates with BMS to adapt to different battery chemistries and voltage ranges.​

Q: How long does it take to switch between charging and discharging modes?​

A: Mode switching takes fast enough to respond to grid fluctuations or load changes.​

Q: Do you offer custom solutions?​

A: Yes-we can tailor voltage, power, topology, and communication protocols to your specific application. Contact our engineering team for a custom quote.​

Q: What is the expected lifespan of the converter?​

A: With proper maintenance, the converter has a lifespan of 15–20 years (MTBF > 100,000 hours).
